Abstract

The invention discloses a pre-stress self-resetting damage controllable spliced swing wall which comprises at least one spliced unit. The spliced units comprise upper connecting beams and lower connecting beams, the upper connecting beams and the lower connecting beams are opposite to one another, two prefabricated walls are arranged between each upper connecting beam and the corresponding lower connecting beam, and an energy dissipation damper is arranged between every two corresponding prefabricated walls; the various prefabricated walls comprise prefabricated reinforced concrete bodies and corner deformation blocks, the corner deformation blocks of each prefabricated wall are arranged at four corners of the prefabricated reinforced concrete body of the prefabricated wall, and the elastic modulus of the corner deformation blocks is lower than the elastic modulus of concrete; non-bonding pre-stress rib pore passages are reserved in the various prefabricated reinforced concrete bodies, non-bonding pre-stress ribs are arranged in the non-bonding pre-stress rib pore passages, and two ends of each non-bonding pre-stress rib are respectively anchored on the corresponding upper connecting beam and the corresponding lower connecting beam. The pre-stress self-resetting damage controllable spliced swing wall has the advantages that the pre-stress self-resetting damage controllable spliced swing wall can be mounted conveniently and quickly and can be used during new construction and reinforcement; swing, lifting, dropping and impact behavior of the spliced walls during earthquake is utilized, accordingly, the structural rigidity can be reduced, structural periods can be shortened, earthquake energy can be dissipated, and earthquake actions can be relieved.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a prestressed self-resetting damage controllable assembled swing wall. Background technique [0002] Earthquakes, as sudden natural disasters, often cause huge social impact and economic losses. Ordinary concrete buildings designed according to codes can no longer fully meet the growing seismic demand of buildings. The structure needs to be under the action of earthquakes and other disasters without excessive damage to the structure, and after the disaster can be repaired under reasonable technical and economic conditions to restore its expected function, that is, the damage controllable structure. [0003] Structural damage is reflected in the overall effect of component damage, including three aspects: damage form, damage degree and damage distribution. The purpose of structural damage control is to limit the damage of the structure to the preset parts, and make the...
